What is the author's style in The Bone People by Keri Hulme?

The language in “The Bone People” is written as it would have been spoken, with explicit words throughout and broken dialect. The author writes in both Maori and conversational New Zealand speech, often making it difficult to understand. The author includes a section of translated Maori words and phrases that are scattered throughout the book at the end of the novel. Due to the explicit speech of some of the characters, this book is suggested for mature audiences only.
